Additional Infomation About Product

SC4525D 18V, 3A, 350kHz Step-Down Switching Regulator POWER MANAGEMENT Features Description Input range: 3V to 8V The SC4525D is a 350kHz constant frequency peak 3A Output Current current-mode step-down switching regulator capable of 350kHz Fixed Switching Frequency producing 3A output current from an input ranging from Precision V Feedback Voltage 3V to 8V . The SC4525D is suitable for next generation Peak Current-Mode Control XDSL modems, high-definition TVs and various point of Cycle-by-Cycle Current Limiting load applications. Hiccup Overload Protection with Frequency Foldback Soft-Start and Enable Peak current-mode PWM control employed in the Thermal Shutdown SC4525D achieves fast transient response with simple loop Thermally Enhanced 8-pin SOIC Package compensation. Cycle-by-cycle current limiting and hiccup Fully RoHS and WEEE compliant overload protection reduces power dissipation during output overload. Soft-start function reduces input start- up current and prevents the output from overshooting during power-up. Applications 1122 The SC4525D is available in SOIC-8 EDP package.
